Area of sector is the amount of space enclosed within the boundary of a sector. Explore and learn more about the area of a sector formula, with concepts, definition, examples, and solutions.
In that scenario, however, a circle will be said to have two sectors where both sectors will possess the same amount of area. Now let us get familiar with the formula for determining the total area of a sector. Let us assume that ‘r’ is the radius of the circle whose sector’s ...
The sector that is being referred to is a sector of a circle. What is the Formula for the Area of a Circular Sector Using Radians? Again, to solve for the area, the central angle and radius must be known. The procedure is similar to what we did in the previous section. We have ...
A circle has an angle of 2π and an Area of:πr2 A Sector has an angle of θ instead of 2π so its Area is : θ2π×πr2 Which can be simplified to:θ2× r2Area of Sector = θ2× r2 (when θ is in radians)Area of Sector = θ × π360× r2 (when θ is in degrees...
